Table 5 shows a comparison of microsatellite locus characteristics across multiple shark species [38] [40], [42], [44], [48] [53].
Additionally, age underestimation has been documented in multiple shark species including long-lived species such as the Porbeagle, Lamna nasus (Bonnaterre, 1788) (Francis et al., 2007) and the Australian School Shark, Galeorhinus galeus (L. 1758) (Kalish & Johnston, 2001), and species with intermediate life histories such as the Bonnethead, Sphyrna tiburo (L. 1758) (Frazier et al., 2014).
